ImGui_GM v1.0.13

howdy y'all, it's been a minute! sorry for not being able to put out as many releases of ImGui_GM as i was before, free time has become a precious asset and so it's been a bit tough finding time to work on this! but alas, this release fixes up some memory leaks pertaining functions with array arguments

Fixed:

• Fixed heap array allocations not being freed when used by certain wrappers
  • This fixes a noticable memory leak with using the ImGui.Image wrapper, along with other wrappers that had argument arrays (sliders, drag inputs, etc)
• Fixed a typo in ImGui.CollapsingHeader that made it impossible to display a header without a close button

thanks for the continued usage and support for imgui_gm, it's been wonderful to see how many downloads the extension has gotten and how many people have been using it for their own projects! special thanks to ocornut himself for adding imgui_gm to the bindings page for the imgui repo :3
